ABSTRACT:
A roll especially adapted for supporting alloy pipe and tubing during travel through an annealing furnace; the roll has a roll body constructed of at least one refractory casting mounted on a cooled shaft and having a reinforcing binder distributed substantially evenly throughout the refractory and a metal surface portion in surface contact with the pipe or tubing; there is no metal-to-metal contact between the cooled shaft and the metal surface portion of the roll body so that said surface portion is maintained at substantially the same temperature as the annealing furnace.
